should climate change be the real issue?

i am a lover of nature. there has been controversy as to whether global warming is caused by industrial activity or caused by the sun's activity. but i think neither of them are the real problem. the real problem is that our current industrial activities do produce millions of tons of bad-smelling and harmful gases and chemicals everyday which absolutely have serious effect on every inhabitant on the earth and their living environment, while the wastes produced by our modern living style should also be considered. it is incontrovertible that the sun's activity plays important role in climate change, but it is also the fact we can do nothing as to it. we cannot manipulate the sun, but we can regulate ourselves. we should focus on the climate change only, since there are still more serious environmental issues, like water and soil pollution. we cannot contribute these issues to other factors like earth or the moon but ourselves. so i think climate change should be the real issue and the real one should be the pollution that industrial activity has produced. am i right or maybe my opinion is a bit extreme. and i really look forward to yours.
